LUBRICA'IING DEVICE.

Application filed October 27, 1922. Serial No. 597,295.

To all whom it may concern:

Be it known that I, FELIX C. HARTUNG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Lubricatin Devices, of which the following is a speci cation.

This invention relates to lubricating devices and the like and is fully described in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a side elevation of an oil cup embodying my invention;

Fig. 2 is a vertical section on the line 22 of Fig. 1;

Fig. 3 is a horizontal of Fig. 2;

Fig. 4 is a view similar to Fig. 2 showing a modified form of the invention;

Fig. 5 is alongitudinal section through an air pipe adapted to be used with either of these forms of oil cup;

Fig. 6 is an end elevation of the same;

Fig. 7 is a artial longitudinal section through a modified form of the invention as applied to a shackle bolt; and

Fig. 8 is a view on the line 88 of Fig. 7.

The embodiment shown in Figs. 1, 2 and 3 comprises a hollow shank 10, the u per end 10 of which passes through a dishe washer 11 and is riveted thereover. A cup 12 passes over the Washer 11 and is spun around the lower portion thereof to retain it thereon.

A tapered oil hole 13 is formed in the top of the cup 12 and terminates in an inwardly extending cylindrical portion which is nor-- mally closed by means of a cylindrical knob lat upon the piston 15, the latter normally being retained in the position shown in Fig. 2 by means of the spring 16. This piston also carries an inwardly extending plunger 17.

A tapered valve seat 18 is formed within the shank 10 and this is normally closed by means of the hollow valve 19 within which section on the line 3 is closely fitted wicking 20, or the like, which cated ears'23 each of which'has a slot 24. extending over pins 25. Springs26 serve to hold these pins at the upper ends of the slots so that when the cover is moved to a position shown in Fig. 2 it will be held down tightly over the top of the cup 12. Felt, leather, or the like, 27, is placed within the cover and a depression 28 may also be provided, if desired, for engagement within the opening 13. The operation of this cup is as follows: y

The operator lifts up on the cover 22 thereby compressing the springs 26 when the cover may be swung about the pins 25 to either side. An oil can spout is then inserted into the opening 13 depressing the ball 14. Oil is then forced into the oil cup which runs down through a series of holes 15 in the piston 15. By pressing down only slightly on the ball 14 the oil cup may be filled with oil without permitting any of it to be forced out past the valve 19. If it is desired, however, that oil should be flushed past this valve the operation further depresses the ball 14 so as to force the plunger 17 against the extension 19 thereby forcing the valve 19 off its seat. Oil will then flow past the valve. Ordinarily only a very slow seepage of oil through the wicking 20 is permitted, the rate of flow being governed by the size and material of the wicking.

In Fig. 4 is shown a modified form of the device in which an extension 27 is provided with external threads similar to those used on air valves of pneumatic tires so that any ordinary air chuck may be pressed over the upper end of the extension 27 and air pressure used for forcing oil through the parts to be lubricated.

In Fig. 7 is shown a shackle bolt 28 having a hollow central portion 29 which is closed by means of a valve seat 30 and a hollow valve 31 which carries a wick 32 and is normally held upon its seat by means of a spring 33. This bolt is provided with an oil cup 35 which communicates through the passages 36 and 37 with the valve 32. A ball valve 38 is provided in the passage 36 which is normally open to permit oil to flow from the cup 35 into the passage 37. An extension 39 is provided with a pin 40 and is adapted to receive an air chuck so that by removing the cap 31 and placing an air chuck thereover, air pressure will lift the valve 31 off its seat and cause oil to be forced through the bearing in which the shackle bolt is inserted. As the air is applied it will raise the ball 38 thereby preventing the air from blowing back through the oil cup 35.

An air pipe 42 is also provided for forcing oil through the parts to which the oil cup, shown in Fig. 2, is applied. For this purpose the end 43 is adapted to fit snugly into the opening 13 while the end 44 is provided with a pin 45 for engaging the cen ter pin of any well known form of air chuck such as is in common use at filling stations.

While I have shown and described but a few embodiments of my invention, it is to be understood that it is capable of many more modifications. Changes, therefore, in the construction and arrangement may be made without departing fromthe spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new. and desire to secure by Letters Patent, is:-

1. A lubricating device comprising a reservoir for lubricant, a valve opening out wardly from said reservoir and communicating with parts to be lubricated, a wick in said valve for slowly feeding lubricant, means for yieldably holding said valve on its seat, and pressure-operated means for forcing said valve off its seat to permit lubricant to flow downwardly and outwardly past said valve.

2. A lubricating device comprising a reservoir for lubricant, a valve opening out- Wardly from said reservoir and communicating with parts to be lubricated, awick in said valve for slowly. feeding lubricant, means for yieldably holding said valve on its seat, and an opening into said reservoir adapted to receive a connection communicating with a source of air pressure for forcing said valve off its seat for flushing lubricant past said valve.

3. A'lubricating device comprising a. reservoir for lubricant, a valve opening outwardly from said reservoir and communicating with. parts to be lubricated, a wick in said valve for slowly feeding lubricant, means for yieldably holdingsaid valve on its seat, an opening into said reservoir, and a spring-pressed member within said reservoir normally closing said opening, said opening being adapted to receive a connection communicating with a source of air pressure for forcing said valve off its seat for flushing lubricant outwardly past said valve.

4. A lubricating device comprising a reservoir for lubricant, a valve opening outwardly from said reservoir and communicating with parts to be lubricated, a wick in said valve for slowly feeding lubricant, means for yieldably holding said valve on its seat, an opening in said reservoir, a spring-pressed member normally closing said opening, and a plunger carried by said member for pressing said valve 05 its seat when the member is pressed inwardly a predetermined amount.
